Seo, Tamae;Ishiyama, Tatsuo;Kubota, Koji;Ito, Hajime research published 《 Solid-state Suzuki-Miyaura cross-coupling reactions: olefin-accelerated C-C coupling using mechanochemistry》, the research content is summarized as follows. The first broadly applicable mechanochem. protocol for a solid-state palladium-catalyzed cross-coupling reaction of arylhalides ArX (Ar = benzothiophen-5-yl, anthracen-9-yl, biphenyl-4-yl, etc.; X = Cl, Br, I) and boronic acids RB(OH)₂ (R = 4-methoxyphenyl, 1-naphthyl, thiophen-3-yl, etc.) using an olefin additive has been reported. Compared to previous studies, the newly developed protocol shows a substantially broadened substrate scope. This mechanistic data suggest that olefin additives might act as dispersants for the palladium-based catalyst to suppress higher aggregation of the nanoparticles, and also as stabilizer for the active monomeric Pd(0) species, thus facilitating these challenging solid-state C-C bond forming cross-coupling reactions.

Sato, Takeo;Shimada, Shigeru;Hata, Kazuo research published 《 Photo-aryl coupling and related reactions. II. Formation of triphenylenes from halo-o-terphenyls》, the research content is summarized as follows. Electronic effects on the photochem. conversion of o-terphenyl to triphenylene were examined by comparing the uv irradiation reaction, carried out in benzene using iodine as an oxidant, of three classes of o-terphenyl derivatives, 4- (I) and 4′-substituted (II) and 4,4”-disubstituted derivatives (III). While a strong electron-withdrawing group such as nitro group, hindered the cyclization reaction to occur, methoxy, fluoro, chloro and bromo compounds afforded the corresponding triphenylene derivatives With bromo and iodo compounds, however, a complex mixture of the products resulted due to photochem. cleavage of a carbon-halogen bonding, which led to the formation of phenylation products and hence phenyltriphenylenes together with reduction products. Further, with iodo compounds, it was found that no oxidant was necessary to effect the cyclodehydrogenation reaction since iodine was liberated during the photolysis. Possible pathways for the formation of the photolysis products from bromo and iodo compounds were discussed in relation to the relative rates of carbon-halogen cleavage and cyclization reactions. Comparison among three classes of halo compounds indicated that, with the exception of iodides, the cyclization reaction occurred more readily with type II compounds than type I compounds, while type III compounds reacted only with difficulty.

Rawat, Vishal Kumar;Higashida, Kosuke;Sawamura, Masaya research published 《 Nickel-Catalyzed Homocoupling of Aryl Ethers with Magnesium Anthracene Reductant》, the research content is summarized as follows. Nickel-catalyzed reductive homocoupling of aryl ethers has been achieved with Mg(anthracene)(thf)₃ as a readily available low-cost reductant. DFT calculations provided a rationale for the specific efficiency of the diorganomagnesium-type two-electron reducing agent. The calculations show that the dianionic anthracene-9,10-diyl ligand reduces the two aryl ether substrates, resulting in the homocoupling reaction through supply of electrons to the Ni-Mg bimetallic system to form organomagnesium nickel(0)-ate complexes, which cause two sequential C-O bond cleavage reactions. The calculations also showed cooperative actions of Lewis acidic magnesium atoms and electron-rich nickel atoms in the C-O cleavage reactions.

The fluorescence quantum yield of triphenylene is low because the transition moment between the HOMOs and the LUMOs is negligibly small. To improve the fluorescence quantum yield, break of the sym. structure of triphenylene is necessary. We found that the rotational effect of the 4-(trimethylsilyl)phenyl groups of 2,3,6,7,10,11-hexakis[4-(trimethylsilyl)phenyl]triphenylene is effective to break the symmetry in spite of the sym. structure, leading to improvement of the fluorescence quantum yield.

Kubota, Koji;Takahashi, Rikuro;Uesugi, Minami;Ito, Hajime research published 《 A Glove-Box- and Schlenk-Line-Free Protocol for Solid-State C-N Cross-Coupling Reactions Using Mechanochemistry》, the research content is summarized as follows. Carbon-nitrogen (C-N) bond-forming cross-coupling reactions catalyzed by palladium-based catalysts, the so-called Buchwald-Hartwig aminations, have been widely employed for the synthesis of pharmaceuticals and aryl-amine-based organic materials in academic and industrial settings. However, in solution, these reactions usually require glove-box and Schlenk line techniques, which greatly reduces their practical utility. Here, we report the development of operationally simple mechanochem. C-N cross-coupling reactions in the solid-state. Intensive investigations of various ball milling parameters revealed that the air-stable ligand tri(1-adamantyl)phosphine can be used to achieve solid-state coupling reactions between aryl halides and diarylamines with high efficiency. Notably, all exptl. operations of the developed protocol can be carried out in air, thus providing a more convenient, industrially attractive, and sustainable alternative to conventional solution-based palladium-catalyzed C-N coupling reactions. The development of operationally simple mechanochem. solid-state C-N cross-coupling reactions in air is reported.

Kubota, Koji;Takahashi, Rina;Ito, Hajime research published 《 Mechanochemistry allows carrying out sensitive organometallic reactions in air: glove-box-and-Schlenk-line-free synthesis of oxidative addition complexes from aryl halides and palladium(0)》, the research content is summarized as follows. Organic reactions that employ moisture- and/or oxygen-sensitive reagents or intermediates usually involve the use of glove-box or Schlenk-line techniques as well as dry and degassed solvents. Unfortunately, these requirements may greatly reduce the utility of the targeted organic mols. Herein, we demonstrate that solvent-free mechanochem. synthetic techniques allow using highly oxygen-sensitive palladium(0) species in air for the stoichiometric oxidative addition of aryl halides. The low diffusion efficiency of gaseous oxygen in crystalline or amorphous solid-state reaction mixtures should be the main reason for the low impact of the presence of atm. oxygen on the sensitive oxidative addition reactions under the applied conditions. This study thus illustrates the outstanding potential of mechanochem. to serve as an operationally simple, glove-box-and-Schlenk-line-free synthetic route to organometallic compounds and other valuable synthetic targets, even when sensitive reagents or intermediates are involved.
